Project GTFD (SVO V6)

DAM!!!!! Cool stuff.

What's the deal with the aluminum pieces seen in the valley in pics #7 and 9? Bracing for strength (like a valley "girdle)? Most of those I've seen go across the block not fore to aft? Looks like you'd have to move the trans crossmember mount, or rebuild it too if you set it back. What the hell man, you've gone this far/crazy, cut the fire wall for clearance and move it as far as you wanna! :D

You have a small fortune in an fittings and ss line. Is your vac pump plumbed straight to the oil pan? Also what are you doing about steering?
 
Looking good. Wow, this is a serious setup ... you will go fast. Not really a street car, is it?!

The new IRS Mustangs use a 2-piece driveshaft with center support bearing to keep critical speed down. Any chance you could adapt something from that program, rather than go custom? Then again, it looks like you haven't really been pinching pennies on the rest of the build.

I would cut it all out if it was legal in any class I'd want to run in! That aluminum piece will help some deflection as the epoxy is meant to make the valley one piece, instead of effectively bracing. Most of its function is to block off the oil from dripping on top of the crank, which frees up HP, especially at high RPMs.

I definitely don't feel like moving it back, but I know I'll kick myself down the road when I have to pay another $1200 for a driveshaft just because of willpower.

The vac pump pulls from the crankcase through the valve cover and then vents to the atmosphere. The line runs into the fender on the other side of the factory battery mount. Gotta save as much room under that hood as possible.

No Mid Plate?

True, it isn't in the picture! I actually forgot to bolt it in and then had to take it all out once I was ready to mount it to the car, haha. I'll snap some pics.

I hope it goes fast! Eventually I want to run Ultra Street (76mm)It will be a true 50/50 street/strip car. Cobra brakes, turn signals, lights, street tires/wheels. Not a daily by any means, but nothing's too radical for the street on it!

I've been pinching quite a bit. The whole build is me sniping parts for the lowest possible cost and best deal I can get, but no it isn't cheap! Some things like the transmission/driveshaft/rear you just can't skimp on, though. Designing and building yourself saves a ton of money.

I considered the 2-piece, but that's extra rotating weight and it ends up being $1k anyways. Might as well go CF for less rotating mass.
 
Interesting coil placement. So does any oil get in the valley and if so how does it get back to the pan? Oh I think I see the hole and the small drain line.

Ultra huh... gotta run 4.90s.:D
 
Yeah there's a -6AN line that runs from the back of the valley to the pan, there's a hole in the front of the valley for the oil to trickle down the front of the block, then there is a -10AN return in each head. I'm not sure how well hot oil flows back to the pan, but 20 degree oil doesn't go back so fast! I might just have to throw an extra quart in the pan.

I'm very stuck in what i want to run. I definitely want to go Ultra, but I want to chase higher numbers at this point, which the 76mm turbo won't push the engine to the limit. I have everything set up for twins, so I'm wondering if I just need to follow through with that. Or else I would be swapping intercoolers and rebuilding other things.

Little update: I went ahead and moved that engine back 1 whole inch. This means that the brake booster gets taken off and I'll have to change to a bigger piston (1" MC piston). Since the factory pedal ratio is 3:1 (which is turrible) I'm going with a Wilwood 7:1 ratio pedal and their MC (http://www.summitracing.com/parts/cmb-14-0016). This is a much better alternative to a low-vacuum engine with cobra brakes. The brake booster would only accumulate vacuum whenever it reaches conditions of cruise RPM and 0% TPS, then it would get used up in one pedal pump.
 
My bro started getting into them. Put a hitch on it and did an engine/brake swap. I got him to do a turbo setup on it, too!
 
Scrap this engine. You need more cubes. I think 560 will do.:D

Lots of stuff since I last updated. Getting pretty close!

I decided to move the engine back to help with the critical speed of the driveshaft and because they're too expensive to buy another and they can't shorten the driveshaft any shorter than 4" at a time! I ordered a carbon fiber one from Mark Williams and it's such a nice piece. It almost looks and feels like a toy, too! This driveshaft is 58" long, u-joint to u-joint, which is crazy long, to me.

I went with Precision 6766s. I remounted them to face forward and to be force fed through the bumper whenever I get more time later to do that modification. There looks like there is just enough room and height for a gravity drain, so I am gonna try it before moving to a pump. These snails should last me a while and let me figure out what the engine is capable of. I'm trying to find their/the engine's limit and also to set the car up for class racing, which requires single turbo. I figured I'd rather buy something that has a lot of power potential in case the car's just too non-competitive for class racing. I learned a lot about the lines and it's funny what manufacturers do. They all just try to save some money and you can tell. The silicone intakes.com PTFE hose is nice, but the hose end's IDs are about .050"-.075" smaller than a name brand's ID. It's really like a -8AN hose end on a -10AN hose. I used that on the oil return from the turbos and am leery of it.

I decided to add a secondary fuel pump instead of doing a cable drive pump. I won't be able to use methanol whenever i go class racing, but it wasn't in my current budget to buy a $2000 pump setup. The dual Magnafuel 4303 setup i have is about half that plus all the lines and fittings. Fuel lines are Fragola PTFE -10AN feeds and -8AN return. After spending an insane amount of money on lines and fittings, I come to find out I could have saved a lot by getting it from Racetronix. Even with my racer's discount. I still didn't get an answer from them about the ID of their -10AN hose ends as an example.

Got the headers all welded up and rainbows for days! Seems as though things shifted around on one side and the pipes are about 1/4" off of the mounts that I made. I can work with it but everything's so tightly fit that there isn't much room for error. The exhaust ports, spark plugs, and header bolts are very close to each other on this motor, making it hard to use a normal spark plug socket even with low profile header bolts. I had to grind some of the flange down and then pull out a ghetto lathe (drill on an angle grinder) on a spark plug socket to get that to work out. I also had some stainless steel, embossed header gaskets made off of the drawings from my header flanges. They're very nice!

Intake manifold and fuel system are all plumbed and ready to go, finally.

I decided to go with 2 A2W intercoolers, which are good for about 1000hp a piece, as long as I can keep them nice and cool. The tank is a Chiseled Performance custom piece with a 3700 GPH bilge pump. That thing empties the 6 gallon tank very quickly! I'm happy with him.

I tried to use the starter that came with engine parts whenever I bought it and it's dragging for some reason, so I'm thinking it's bad. There is a secondary 4 gauge ground from the starter to the battery, so that should be fine. I might either need to take it apart and see what's up, take it to a starter/alternator guy, or just buy a new one. The battery is new as well as everything else, so the system output is just fine.

I have a decent amount of stuff to do before the Shootout....

Install interior
finish engine wiring
complete bolting on turbo setup (easy)
cutting hood for downpipes and intake
Hood pins
seat belts
bleed front brakes
set ride height
test fuel system
test that all outputs work from ECM
Install EGT setup
Put in break-in oil, trans fluid, and rear end fluid
plumb and mount boosht controller
TUNE IT!!

I'm probably being optimistic about this year but we'll see! Pretty close to starting it.







































 
I still read the Forums.

I'm still reading the forums. This is a great thread with lots of great photos of some really creative engineering. If there was a poll for best thread, I'd give it my vote!
 
I've been under the gun nearly every year to get to the shootout. I really hope this car is there Casey, it's one of the reasons I go is to see all of the cool things people have put there blood sweat and tears into. I've done alot of work to mine this year but the work you have put in on this car is above and beyond my friend.

I've been dying for an update on this project for some time now. Perhaps you've been updating the status another way, or I simply just missed it.:eek:

Truly impressive work you've done here. From a fellow fabricator and Mechanical Engineer, it's awesome work. Looking forward to your continued updates and to seeing it lay down some smack at the track.

One thing is for sure....I've got A LOT of catching up to do. You and Brian have set the bar high for potential quick cars and I hope to join the 9.50 club someday.
